Specification ofLetters 2mm.

Application filed October 28,1912. Serial massages Be it known that I, BAKER, of the firm of Joseph Baker & Sons, Limited, a subject of the King of England,

residing at London, in England,- have invented certain new and useful Improvements in Biscuit-Wrapping Machines, of which the following is a specification.

This invention relates to improvements in machines for wrapping biscuits and the like.

The biscuits are fed by a slide which carries them with a sheet of wrapping paper along a table over a box or chainber, where they are "gripped by end holders or pressers which hold them in compact formation and carry same -into said box with the paper which incloses the biscuits on certain side's. Theflend holders retain the biscuits in said box compactly together until certain folds have been given to the paper by appropriate devices suflicient toprevent the biscuits getting out of place whereupon the packet thus far produced is moved further between spring pressed guides to complete the fold I ing, and thence to a labeling device by" which a label is attached to each end of the packet. After this operation the labeled packet is forwarded and discharged from the machine,

being however held between endless traveling belts for suflicient time to enable the gummed labels to adhereor become dry.

A practical embodiment of themachine is V shown in the annexed drawings in which-- Figure 1 is aside elevationIand Fig. 2 a plan showing the generalz arrangement of the machine, many of the'parts'being omitted for the sake of clearness of illustration. Figs. 1 and 1 are detail views of suctiondevices hereinafter describedwhichact on the paper during feed thereof.

The plate 11 1s pressed down on p to the paper at the-correct time by means of a lever 18 mounted on shaft 19 (Fig 1 which is rocked by lever 20 and rod 21 connected at its opposite end to a spring pulled bell crank 22 acted on by a cam 23 mounted on a shaft 24, the valve in the valve.

The carriage 28 is mounted to run in -lat-- eral guides 29 on the machine frame and is provided with an abutment ,30 which on rearward movement of the carriage engagesa resilient buffer 31 carried by a cross bar 32 mounted on the frame. The reciproeating movements of the carriage may be produced by any convenient means, those shown in the drawingsincluding a link 36 connected to,the carriage a curved lever 37 pivoted on a shaft 38 on Which are mounted two diverging arms39 actuated b a double acting cam 40 on a transverse s aft 41. The said carriage 28 is provided at its forward end with spring clips 33 which reccive between them the biscuits to be forwarded to the wrapping position, said hiscuits resting on a base plate 35. The car rear member to enable the forward end of the sheet to be supported by and above said forward member. The connection between the two members is so made that therear member moves first to bring the forward part of the sheet on to the forward member of the slide and then permits the two members to move forward together to carry the sheet into the position in which the wrapping is effected. This is accomplished by providing on rear member 43 a lug 45 adapted to slide on a rod 46 connected to the front member 44, the latter also carrying a second lug 47 between which and the lug 45 is a spring 48. On rearward movement of the slide a pin 49 projecting from the lug 47 engages a book 50 attached to the paper box 3, thus causing the spring 48 to be compressed and toward the termination of said rearward movement causing both slide members to move together into the normal position shown in Figs. 7 and 8. During the first part of the forward slide movementthe leg 45 slides on the rod 46 and allows movement of the rear member without affecting the forward member until said lug 45 engages another lug 5.1 on the forwardv member whereupon the two members move together. This primary movement of the rear member causes the front 'edge'of the paper sheet to be brought on to the forward bar 44 of the front member,

the two slide members moving together as plan only one half thereof. The bar 44* of thefront slide member is recessed as at 52 for the purpose of clearingcertain fold holding fingers hereinafter referred to.

During the rearward moyement of the carriage 28 and slide 42, it is necessary to slightly depress and grip the stack of paper 1 in order to prevent the upper sheet being drawn off by the slide and to this end thereis provided, one at each side of the-box 3, a device shown in Figs. 5 and 6; comprising a gripper 53 .spring hinged at 54 to a slide 55 mounted in. a guide bracket 56 on the side of the-paper box 3. I The gripper is shaped uto extend over the upper edge of the box and engage the surface of the top sheet and the spring hinge tends I to normally hold the .gripper out of action, but the same is brought into action at the proper time (and when the table 2 has been released from the gripping arm 8) by means of an arm 57 having a roller 58 which on ages a curved surface 59 of the grip er. f' aid arm and roller are stationary an secured to [the bracket 56 and the gripper is ada ted to be given vertical movements in said racket by means 7 of a rod"59-seoured to the slide55 by a springGO and a lever 61 operated by a cam 62 mounted onthe aforesald shaft 10*. After the rear edge of the top'sheet of paper has been"raisedto the suction. plate 11, a third clip h fl) similar to 53 and working 130.

' second sheet to' prevent this and the sheets struction also two spring any convenient manner, this action opening bolt 74 engaging a notch 75 in;,,th'e rack so mal position the clipsremain open for re- .ing part of the caTrriage 28, the resilient 'of the clips.

rant 68'- meshing with a rack 69 mounted I the projecting end of the rack is depressed tending across smart alternately with same, comes into operationl to press upon the rear upper surface of the below from being removed with the top sheet by the movement ofthe slide.

Figs. 9 to 11 show 'a further embodiment of the biscuit gripping means. In this conclips 63 adapted. to grip the ends of the biscuits m (Fig. 10) are employed mounted in a frame 70 formaction ofsaid clips being produced by a torsion spring 64: coiled about ashaft 65 provided at each end with a bevel wheel 66 which meshes with another bevel wheel 67 mounted on a spindle '68 each carrying ,one

On shaft 65. is-a toothed quadin frame 70. -When the clips 63 are in the gripping position shown in Fig- 10 the rack 69 projects above the frame as in Fig. 11 and in order to release the biscuits from the clips when they arrive in wrapping position,

by' a finger 71 mounted on a shaft 72 exthemachine and rocked by means of a lever 72 and rod 73 operated in the clips through the,quadrant 68, shaft 65., gears 66, 67 and spindles 68. The rack is held in its depressed position by a spring that during return of the carriage t0 norception of another batch of biscuits. When said hatch has been inserted the operative releases the bolt 74: by means .of a spring finger piece 76 connected thereto, thus causing the clips to grip the ends of the new batch of biscuits. "When the biscuits and paper have been fed by the forwardmovement of the carriage 28 and slide 42 to the wrappingposition below the cross heads 77 and 7 8 method in Fi 1, the biscuits are gripped by the'enjd hol rs 99 and:100 hereinafter described, which are moved toward the center and act to keep the biscuits in compact formation while the clips are released and the feed slide and carriage re-- turn to their original positions, as above mentioned. I I I The paper is prevented from being fed too far forward and is properly positionedby engaging stops 79 on a bar 80 extending across the machine and in order to prevent the paper being drawn back during the rearward movement of the feed slide front edge thereof is gripped for example in two places-one at each side by a finger 81 more particularly shown in Figs. 23 and 21. These fingers are supported by a trans-' verse rod 82 at each end of which is a lever 83 having a plate 84 which isdepressed by an abutment 85 on a cross head 86 (herein- 42 the" down upon the forward edge of the paper. The fingers .are locked in this position meansof a double-toothed catch 87 (Fig.

icngaged by a spring bolt 88 which holds the lever either in raised or lowered position. Also mounted on the pivot of lever 83 is an arm 89 in a plane outside the mafingers from the paper by a curved block 90 on alever 91 (Fig. 1) the purpose of which willbe explained below.

from the clips they are moved toward the center of the machine into the position shown in Fig. 30 and abut against the end biscuits of the stack so that the biscuits are I held in correct position over a box or chamber 98, whereupon the holders move downward with the biscuits'and paper into said chamber which is formed in a slide 93 (Figs. 26 and 27) adapted to reciprocate to and fro in a plane'below that of the feed slide 42. The slide 93 comprises a base plate 94 having a sliding false bottom 95 and the space or chamber is bounded at the rear by a plate 96'and at tongues or sections 97.

The means for operating the end holders 99; and 100 is as follows :-Garried by the cross head 7 7 before mentioned are pairs of. tubes 98 (Figs. 30 and 35) to the lower ends of which are rigidly secured the lower holders 99 and slidably mounted on said tubes and under the action of springs within same are the upper holders 100 the springs tending to normally keep said holders raised as in Fi 30. Each opposite pair of tubes is mounted in a separate rack bar 101, 102, (Figs. 32 to 34) having teeth 103 at dilferent .from'the biscuits. The spindle 105 is provided with a feather 109 sothat the cross head 77 can have vertical movement without interfering with-the operation of the bevel wheel 106v and the shaft 108 is rocked by means of a quadrant 109" (Fig. 1) meshing with a rack 110 operated in one direction by a rod112 acted on by a cam' (notshown) on the shaft 24' previously mentioned, and in the other'direction by a spring 114. Fig. 33 shows clca'rly the manner of mounting the rack bars 101, 102, in the cross head 77, the side bars 1150f the latter being hollow for reception of the racks which have flanges after fully described) bring the fingers 116 guided'in said side bars. The cross head the front by a series of spring pressed levels as shown more particularly in Fig. 34

'eration to be performed is the folding of the vto the jaws by means of supporting mom-J 77 also supports .a presser plate 92 which is caused to press upon the biscuits and aline the upper edges thereof while they are held by the end holders 99, 100 as explained. The plate 92 is carried by tubes 230 mounted in cross frames 231 straddling the side bars 115 of the upper cross head so that parts 232 thereof lie in the path of the side bars 233 hereinafter explained. The plate 92 is loosely carried by the tubes 230 and is under the action of buffer springs contained within casings 234 tending to hold the plate normally in its lower position and allowing the pressure thereof on the biscuits to be resilient. The cross heads 77 and 78 may be operated by any suitable mechanism but in. Figs. 1 and 2 there are shown-for this purpose, rods 235 and 236 respectively one ,rod. of each at either side. of the machine, said rods being connected to levers 237,- 238 mounted on a shaft 239 which is' oscillated;

roduce the falling and rising movements o' the cross heads for example by cams (not shown) located between the side frames of the machine in a manner which will be clearly understood The cross heads are guided in their move ments by rods 240 connected above by a transverse beam 241.

The paper and. biscuits having been brought into the chamber 98 as described positions shown inFig. 13 and the next oppaper over the top surface of the biscuitsreferred to as top folding. Figs. 14, 15: and 16 show diagrammatically stages of the folding operation and Figs. 19 to 22 show the top folding mechanism.

As shown in Figs. 19 and 21 the 'left hand pivoted an upper blade or jaw 244 and hav--' ing fixed thereto a lowerblade or jaw 245;: the upper jaw being under the action of a spring 245 tending to normally keep the; jaws open.- At. the rear of the plate is an; inclined abutment 246 adapted to be engagedj by a similar abutment 247 on atransverse} bar 248. Figs. 20 and 22 show the right; hand folder 249 which comprises a single pivoted blade or jaw 250 under the action" of a spring 250 tending to hold it down-f ward and having a tail piece 251 which is: acted on by a curved abutment 251 on :15 transverse bar 252. The folders and-bars: are suitably guided at-their ends'in-the ma-j chine frame for reciprocating movement therein and .are given these movements at? the desiredv times by any suitablemechanism, Fig. 1 showing levers 253.Lconnected. by: links 254 pivoted to the ends of the bars! medi'atcly behind the levers 253- connected bers 255. The levers are operated by 5 propriate means such as cams between the side frames in amanner which will be readily understood.

Referring now also to Figs. 14 to 16, the folders 242 and 249 move toward the right and left respectively into the posit-ion shown in Figs. l4*and 15 thus making the first folds a a the blade 250 being then withdrawn and slightly tilted by its tail 251 coacting" with the abutment 251*? so that it. will ride over the portion?) of the fold, when again moving toward the left at which time it presses down the portion of the fold marked 0. The blades 244 and. 245 are now caused to close by the coaction of a tail piece 256 on blade 244 coacting'with an abutment 257 on the bar 248 and move farther to the right, the blade 245 being lifted by means of the coacting abutments 246,247 5 and turning the fold member a a completely over the rest of the fold into the position shown in Fig. 16 the jaws being opened and the blade 250 at the same time withdrawn toward the right. The blades are provided in their adjacent ed es with recesses 258 to clear fold holding 1 gers hereinafter fully described. a During production of the top fold'as just described the presser plate 92 has been 95 Figs 30 d 36) each of which is slida y mounted in a tube-230 and capable of pass- 1 ing through the presser plate 92 into the, pe-' sition shown in broken lines in Fig.fi30 The finger 260 is under the action of a. spring 261 normally tending to force-the finger downward into such position bntprevented from doing so by a tappet 262 .on the finger engagedby a. springbolt 263. Therod is released to allowthe spring to bring it into operative positio'n'bythe following I means (see Fig 30 and 37). The bolt is provided with a bell crank lever 264'one arm'of which is bonnected to the-bolt and the other arm lies in the path of til-"Stop 265.

on the bearing 266 of thespindle 105. As 1120 the lower cross-head78 rises as above (10:. I scribed. the bell crank lever 264 engagesithei step 265 thus withdrawing. the bolt 263 and permit-ting the spring 261 to bring the fin"- ger into the dotted line positionof Fig.- 30} .125,

To again raise thefinger to. normal position illustrated in Fig. '36, the tappt-262 is 0011-. nected by a link 267 to adoublea'rmed lever 268 carrying an antifriction roller 269;.and

mounted in a bracket 270extending froin a no cross frame 231. On a; subsequent upward movement of the cross head 7 7, the roller 269 engages an abutment 271 depending from the cross beam 241 and thus lifts the finger, the again arrested by the spring bolt 2'63 engaging under the tappet 262. It will be seen from Fig. 30 that there are two fingers 260. the above description serving for both.

The nextoperation to be performed is the produc on of the top end folds of the packet marked d in Fig. 17 and this is ef- {fected by the following means (see Figs. 30, 31 and 35). The lower cross head 78 in addition to having theside plates 233 above referred to, is provided with end members 272 the latter being at a lower level than said side plates. Screwed into each end membe'ris a rod 273 carrying two telescoped sleeves 274: and 275 respectively. The outer of said sleeves 274 carries a folder block 276 slidably mounted on red 98 before mentioned and having an inwardly projecting finger 27 7 adapted to engage the end of the packet. The inner sleeve 275 carries a tliin plate 278 under the action of a' spring 279 tending to force same mward but normally held from such inward movement by any convenient form of spring catch (not so doing releases the spring catch and per (marked 6' in mits the plate 278 to press firmly against the end fold to compact and finish'the same. The plates 278 remain in this position during the production of Fig/17 which is the, next wrapping operation to be erformed and which is carried out as to ows, reference ends and vforming the being directed to Fig. 27. This fi' ure shows in broken lines a transverse raine. 280 which is capable of being reciprocated' horizontally at the required times by any convenient means not shown). This frame has two forward y extending arms 281 one at each side and carried by these arms are pivoted blades 282. having curved forward folders which blades are under the action of springs contained within casings; 283 connected at' op osite ends'to the arms and blades. It willbe obvious that as the frame 280 moves for,- ward that isQto the left in Fig-27, the blades 282.,will resiliently engage the ends of the packet and act on the paperto produce the downward movement of which is the back end folds lback end folds e the stroke of the frame 280 being controlled to prevent the blades reaching the paper which will subsequently form the front end fold. After production of folds e as described, the plates 278 are raised together with block 276 by the upward movement of cross head 78' and the packet is now ready for production of the .front end folds marked in Fig. 17 which are simply produced by forwarding the packet in. the chamber 98 between lateral plates 284 having curved forward ends pressed by springs 285 toward the center line of the machine as shown. in Figs. 26 and 27 The packet is now in the condition illustrated in Fig. 17 and the only remaining fold to be dealt withis thebottom end imoving the packet downward into a delivery slidefillustratedin Figs. 28 and 29 located below the slide 93 and comprising a base 289 at the forward end of which is a cage consisting of a back member 290 and two open ends formed by hinged members 291' having curved surfaces292 to permit. of easy insertion of the packet, said members 291 being under. the action of a spring 293 to produce resilient pressure on the ends ofthe' packet. The downward movenie'nt of said packet is roduced by means of a presser plate 286- Fig. 2) carried by lugs 287 9 extending fromtthe cross-head 86 before referred to and in *order packet shall have access to said. delivery slideqit isnecessary that the false bot-tom 95 which the packet has of the chamber 98 in been held up to now shall be movedbackward, that is, to the right in Fig. 26, and to effect thisthe said bottom is provided with a lu 294 which as the slide 98 moves forwar engages a suitable abutment in its path, the bottom being again-returned to normal ,positionby'said lug engaging another abutment on the return movement in a a er v'vh ich will be readily understood.

he delivery slide is connected as by plate 295 and rod 296 to a lever 297 outside the 1 machine frame, 'saidlever being mounted on a shaft 298 rocked at the required times 7 as by a cam located between the side frames of the machine. 'as-operated" an vupward direction by means of a rod .299 and lever 300 one: at each side of' the machine, the levers being on a cam ,operated shaft 30l,an d in a downward dir a ya Pm B a I e the packet is in the delivery slide a label is attached to each end thereof over the end folds shown at hin; 18, this being effectedtas-follows with re erence to Figs. 33 wiser the drawin The labels are stored in cylinders 303 at each side of interiorly with very fineibrushes' 304 to re tar d' any undue action the machine,] the cylinders being provided fold g, this being also simply closed by that the The cross ,head 86 is shown of the suction wan drawing means described below. At the bottom of the label cylinders are a number of small protecting lips 305 which engage tion blocks 307 by means of an eccentric quadrant 308 '(Fig. I), mounted outsidethe machine frame on lever 91 and having a groove 309 which engagesa stud 310 on the cylinder.. The suction blocks have perfo rated tops 311 as shown in Fig." 45 so that when suction is exerted thi'ough the blocks by' means of flexible the suction boxes to the valve box 16 before 2 referred to a label will be removed from each cylinder 303. The cylinders now rise again leaving the label on the suction box. The suction boxes are mounted by means of trunnions 313 on slides j 314 to which the flexible pipes 312 are connected. The slides run in guide slots 315 in cam plates 315 and are moved toward the center of the machine by meafis of rods 316 pivoted at the bottom of the machine, normally held toward the 39 machine center by springs 317, and pressed apart away from the center by means of cams 318, operated at the required times.

by any convenient means. The said rods are connected to the sides 314 and the suction boxes are carried by said slides and have friction rollers 319 which engage cross v cam paths 320 in the plates 315". The rollers on the boxes engage the cam paths in such a manner that as the slides are moved 40 toward the center of the machine they are tilted through an angle of 90 as shown in broken lines in Fig. 38. This brings the label, still held on the suction block, on to the end of the packet lying between the blocks, and during thisforward movement and,before the tilting of the suction block takes place, the labelon the end of the block is caused to travel under a gumming roller 321 mounted in a trough 322 and receives a coating of adhesive by which it can be stuck on the end of the packet. T6 produce rotation of the gumming rollers the rods 316 terminate at their upper end in quadrants 323 which engage, pinions 324: on the axles of the guimmng rollers, so that these are rotated at each action of the labeling device. On return of the suction blocks, the gumming box is lifted to clear the suction box by means of a sniall cam path 323 at end of rack and is retained in this position by means of a 'double s ring catch (not shown) until the suction bbx has passed it. The gumming box is returned; to its gumming position by the downward motion of the label cylinder 303, this being brought piping 312- connecting about by a small projection 303 on theside of cylinder 303 engaging with a-similar projection 303" on the ,gumming box. At or about the time the tilting position is reached the suction on the boxes is automatically removed, this being produced by proper operation of the valve in the valve box 16.

. The cylinders 303 may be'provided with inspection slots 325 for viewing the labels therein to determine when the cylinders require recharging. After the labeling and gumming operations the packet of biscuits is discharged by forward movement of the delivery slide on'to a horizontal endless web 326 and at the same time between lateral g endless webs 327' which hold the labels in position until they have adhered sufficiently to the ends of the packets. The web 326 is mounted on rollers 327 and is operated by pawl and ratchet mechanism 328, driven by 5 rod 329 from lev'er- 297 before mentioned. The lateral webs 327 are pressed toward. the center of the machine by boards 330 under the action of springs 331 so as to press the labels firmly on the ends of the packet. The rearwardpulleys 332 carrying the webs 327 arepressed toward each other by springs 333 and the axles ofthese pulleys are pro vided with ratchets 334; with which engage retaining pawls 335 to prevent back movement of the webs. The packet is now completed and may be removed from the web 326 by hand or otherwise. I i
